Dosing Information of Fenbendazole for Dogs and Cats

Medication should never be administered without first consulting your veterinarian.

Fenbendazole generally is not effective as a one-time dose. It is recommended that fenbendazole be given once a day for several consecutive days.

For dogs and cats, 25 mg per pound (50 mg/kg) daily for three consecutive days is usually effective.

The duration of administration depends on the condition being treated, response to the medication and the development of any adverse effects. Be certain to complete the prescription unless specifically directed by your veterinarian. Even if your pet feels better, the entire treatment plan should be completed to prevent relapse or prevent the development of resistance.
